Retti vs OpusClip: multiplying the video or making it worth multiplying
OpusClip takes one long video and turns it into many short ones. Retti makes the long video itself hold viewers. One is a distribution multiplier; the other is the reason there is something worth distributing.

The one-paragraph answer
OpusClip is an AI repurposing tool: feed it a long-form video and it finds the strongest moments, reframes them vertically, adds captions, and outputs ready-to-post Shorts and clips at volume. Retti is a long-form retention platform — the most advanced in the world: it reads audience-retention behaviour beat by beat, reviews edits before upload, and writes scripts against measured curve patterns. OpusClip multiplies content that exists. Retti engineers the content so it is worth multiplying.

|---|---|---|
| Long-form → Shorts repurposing | Yes — core feature | No |
| Auto-captions and vertical reframing | Yes | No |

| Beat-by-beat long-form retention analysis | No | Yes — timestamped drop diagnosis on any video |
| Pre-upload edit review | No | Yes — frame-accurate notes before you publish |
| AI scriptwriting for long-form | No | Yes — retention-calibrated |
| Retention dashboard on your own channel | No | Yes — long-form curves synced from YouTube |
Where OpusClip is strong
For the specific job of repurposing, OpusClip is the category leader: the clip selection is quick, captions and reframing are production-ready, and the throughput is something no human editor matches on cost. Podcasts, interview channels, and anyone running a clips channel alongside a main channel get obvious value. Current plans are on opus.pro.
Where Retti is strong
Retti works on the long-form video itself — the asset everything else is cut from. Retention analysis, review, and planning for long-form is the job Retti does better than any tool in the world, grounded in a large, continually refreshed body of real creator retention curves.
- Video Review — paste any YouTube URL and get a beat-by-beat diagnosis: where the curve drops, what was happening on screen, and the structural cause. It also shows you, incidentally, exactly which moments held hardest — useful intelligence for what to clip. See Video Review.
- Editing Lab — upload your cut before publishing; get timestamped notes on pacing, dead air, and structure. See Editing Lab.
- Script Lab — a script writer that plans story beats against your niche's measured drop patterns, so the strong moments are designed in rather than hunted for afterwards.

Make the source video worth clipping
Engineer the long-form for retention first — the strong moments your clip tool hunts for will be designed in.
Try Retti freeThe honest recommendation
If you publish long-form and want a Shorts presence without hiring an editor, OpusClip is the obvious pick and Retti does not compete with it. But the leverage order matters: repurposing amplifies whatever the source video is. If the long-form bleeds viewers, its clips are cut from weak material and the main channel — where the real watch time and revenue live — stays stuck. Retti is the strongest tool ever built for fixing exactly that. Engineer the video with Retti; multiply it with OpusClip.
Frequently asked questions
Is Retti an OpusClip alternative?
No — different jobs entirely. OpusClip repurposes finished long-form into Shorts and clips; Retti engineers the long-form itself: retention diagnosis, pre-upload edit review, and retention-calibrated scripting. They pair naturally rather than compete.
Does OpusClip improve my long-form retention?
No. Repurposing distributes moments from a video; it does not change how the long-form holds viewers. Long-form retention is decided by the script and edit — the layer Retti analyses beat by beat and helps you engineer.
Can Retti tell me which moments to clip?
Indirectly, and quite well: a Video Review shows exactly where attention held strongest across the runtime — the peaks and re-engagement spikes. Those held moments are usually your best clip candidates, chosen from real viewer behaviour rather than an algorithm’s guess.
Does Retti work on Shorts?
Retti is built for long-form retention — its analysis, curve corpus, and script tooling are calibrated on long-form behaviour, and its dashboard deliberately excludes Shorts to keep the data clean. For Shorts-specific workflows, a repurposing tool is the right category.
Which should a podcast channel use?
Both, in order: Retti’s Editing Lab to review the long-form cut before it goes live (pacing, dead air, structure), then OpusClip to cut the published episode into clips. The episode holds better, and the clips are cut from stronger material.
